This cooking-top unit. is orin front elevation and partly in'cross-secganized in any suitable manner to provide t tion on the line 3-3 in Fig. 4;. Fig. 4 a central solid-fuel portion and side por- 4| is a lo 'tudinal sectional view on the line lions having a dilferent type of. heating- H in ig. 3; Fig. 5 is a detail view on units, preferably gas burncrs. The solid-' the. line 5-5 in Fig. 1 showing the reversifuel portion comprises an ash-pit 10 and a his manifold and its gas-burner valves fire-box 11 of usual rectangular-form and Iin t "r two positions in full and dotted assembled together in an suitable manner so lines respectivel Fig. 6 is a detailed view and having a .cast'meta front frame 12 v of the geomani old with one of the burner secured thereto provided. with the usual opening in its lower to the interior, the ing being hinged to the frame 12.

gortion to aflord access oor 13 for this enash-pit is provided with the usual grate- 18, and may have suitable inlet and outlet assages for a hot-water coil 19.. The firebox has a cast-metal rectangular top bolted to it and provided with the usual short-center 21 and a pair of standard solid fuel cooking openings closed by lids 22. The cast ashpit bottom 23 is secured to the base 1 by removable bolts 24 arranged at its front. and rear and entering bolt holes in the front and rear rails of the base; the outer lateral pair of bolts 24 enter the outer lateral pair of holes 9, and the inner lateral pair of bolts 24 enter holes arranged in opposite pairs 25 and 26, in the front and rear rails of the base, according as the section 2 is mounted at the right or left hand end of the base, the holes 25 and 26 being spaced inwardly or along the length of the base from theaouter holes 9 in correspondence with the spacing of the frontand rear bolts 24 from each other.

The front frame 12 is provided with lower ears 27 which are bolted to the base, the latter being rovided'at each end with a pair of bolt oles 28 and. 29, respectively, the holes of each pair being spaced apart to register with the ears 27 when the section 2 is assembled on the corresponding end of the base. The section 2 is provided with a perimetral main top composed of a front rail 30, rear rail 31 and end rails 32, all preferably cast integral; the front and rear rails extend laterally at each side beyond the fire pot. as shown in Fig. 8, so that with the end rails 32 they form the tops of the burner-boxes on opposite sides of the firebox. The front and rear rails of the main top are provided with inwardly extending depressed flanges to seat tlieends of the fire-box top 20 and the ends and outer sides of the usual burner-box-top rates or grids 33 flush therewith, and the sides of the top 20 are similarly constructed to seat the inner sides of the grids fromfront to rear. The

- front rail is bolted to the upper end of the frame 12, and the rear rail 31 seats on the rear end of the fire-box. The' frame of the cooking-top unit 2 is thuscom osed of the front-frame 12 of the solid-fue portion and the main topnof the burner-box, and is secured to the front rail of the base 1 by the ears 27. The rear rai l.31 of the main top is secured to the rear rail 'of the base by a pair of angularly disposed aces 34 the upper ends of these braces are bolted tothe.

rail 31 near its outer ends, and tliei ,(ower ends are detachably bolted to the base-rail near its end corresponding to the right or 'with bolt-ho es arranged in end pairs 35 and 36, as shown in Fig. the holes of each pair being spaced apart on each side of the center .line of the ash pi't when the latter is mounted above them as shown in Fig. 3. By this construction the braces for the main tg'p are secured interchangeably in the holes 35 and 36 when the section 2 is reversely mounted in position at the corresponding end ofthe base. It is noteworthy that the solid-fuel section occupies a central position with respect to the assembly of the duplex-fuel cooking-top unit 2 and forms the main sup port for the super-structure of the unit symmetrically balanced thereon, as will be understood from Fig. 3. The braces34 lend additional support and serve effectively to prevent racking of the structure. Additional advanta es of the arrangement here described will e mentioned later. It ma be stated, further, that the ash-pit afi'or a broadl based sup ort for the fire-box, and

box, which as its walls formed integrally with each other, affords, in turn, a staunch support for the main top-frame of the duplex cooking unit.

The section 2 is provided with a sectional burner-box having its section arranged at the sides of the fire-box to accommodate the grids 33 and burners 37, these boxes being f organized in a unitary structure with the cast-metal front-frame 12 and other parts of the cooking-top unit, so that the duplexfuel section is supported as a unit at its lower end on the base, and is secured in lace by the bolts 24, cars 27 and braces 34. achsection of the burner-box is rectangular and formed with sheet-metal side walls 38, bottom 39 and rear wall 40 the latter having a series of air inlets 41 as shown in Fig. 3; these parts are suitably secured at their upper portions to the fire-box and'main top, and each section is open at its front and has an L-shaped cast-metal front frame whose horizontalleg 42 is bolted to the front frame 12 and whose vertical leg 43 is secured to the side rail 32'off the main to the parts being arranged with the .burnerx spaced. above the base and approximately in line with the upper portion of the broiler ovenso that the burners 37 are in 'the horizontal plane of the oven burner 44, as shown for example in Figs. 1 and 2. The burners 37 comprise the usual giant burner and three regulation burners to afford the standard top-cooking capacity of the commercial gas-range; a simmering burner 37' may be used, and all the burners are of the usual blue-flame t having integral air-mixers as indicate in Figs. 1 and 2. At the front of the humerbox and of the oven unit a gas-supply manifold 45 is reversibly mounted for supplying all the burners; it is provided with a valvs l llt burner-boxburners.

By organizing the duplex-fuel unit with the solid-fuel portion between the sections of the open-front burner-box and construct ed to be supported'at its lower end on the base, it is possible to place this unit flush against either a right or left hand oven similarly supported on the base and so to standardize the units for interchangeable relation and enable the duplex-fuel range to be changed from a right to a left hand oven and vice versa without using any extra parts, and in either case the gas burners in the burner-boxes are in line with the oven burner and all the burners and the hard-fuel heater can be used at the same'time and a warming chamber is provided. This interchangeable feature is important and advantageous to the manufacturer, the dealer and the user. By my invention the manufacturer is required to make and carry in stock only a single supply or line for both right and left hand oven duplex-fuel ranges and can dispense with the expensive duplicate patterns, molds and operations required for the different kinds: all his appliances and operations are standardized and limited to a single line or type, and all his supply can be mounted and shipped out in either form or in both forms as desired. Also, the dealer or retail merchant need not carry separate stocks of right and left oven duplex-fuel ranges, but can limit his stock to a single line and can fill orders from users for either right or left oven ranges. Further, the user can utilizethe same duplex-fuel range in kitchens where the plan or equipment makes it rlr-sirablc'to have eithena right or left oven range set in one or another particular location; the range can be appropriately set up without requiring an exchange or the purchase of additional parts. Also, considerable floor space is saved as my range can be set with its cooking top against a wallof the kitchen as the outer burner-box section spaces the fire-box far enough from the Wall to prevent damage; and the fire-box is exposed all around and permits the heat to radiate from both its sides, so that the hard-t fuel section is doubly serviceable for heating thekitchen. and a warming chamber is provided in either arrangement of the sec tions. By my invention the duplex-fuel range. can !be set with its cooking top end against the wall to 'savefloor space, and it affords radiation of heaton both sides of the hard fuel portion, and acornplete duplexfuel cooking range and kitchen heater reversible for either right or left hand oven is provided as one unit.

An additional advantage which inheres in the relation of the sections of the duplexfuel cooking-top to each other is that space is gained by the interposition of the fuel section top between the flanking grids which are dis osed above the non-solid-fuel burners, ore ements. This enables larger vessels to be placed over the burners and enables the handles of vessels to project over the solid-fuel section top-a result not attainable (assuming the same sized. sections) where the interposition of the solid-fuel tion is not employed.

The gasburners are merely typical of a. convenient form of heating unit for the cooking to i and the ovens, as these parts may have heaters of any suitable type, for example by placing electric heating units where the gas-heating units are shown,

This application is a continuation in part of my c-o-pendin application filed July 2, 1921, hearing Senal Number 482,130.
